CHAIR-OPERATED FAN.

. Applicationfiled January 6, 1916.

To all whom it may concern Be it knownthat 1, ANTON: ZUBRYD, a subject of the Emperor of Austria-Hungary, residing at Castle Shannon, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Chair-Operated Fans, of which the following is a specification.

This invention relates to certain new and useful improvements in chair-operated fans.

The primary object of the invention is the provision of one or more air circulating fans which are automatically operated-during the usual movements of a rocking chair under the impulse of the occupant and whereby a circulation of air is effected for cooling the said occupant.

A further object of the device is to provide a chair-operated fan mechanism whereby the operative revolutions of the fan will be uninterrupted during the rocking movements of the chair and the speed of the fan is regulated by the rapidity of the rocking operation.

It is also designed by the present inven-.

tion to have a uniformly driven air-circulating fan propelled in such a-manner by the rocking movements of the'chair as to con-' tinue its operations uninterruptedly during any temporary cessation of rocking by the occupant.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the severalviews: Figure 1 is a side elevation of a rocking chair provided with the present device. Fig. 2 is a front elevational view thereof. Fig. 3 is an en larged detail view of the driving members and shaft of thedevice detached and partially broken away. Fig. 4: is a substantially horizontal sectional view through a side por tion of the device, and, Fig. 5 is a perspective view of the floor-engaging lever and re- Specification of Letters Patent.

turn rod detached, the latter being broken away. I

i It being understood that the-present fanoperating device is, readily adaptable forany form of rocking chair, the same is herein illustrated in connection with the chair 10 of the usual construction and having curved rockers 11 by means of which the chair is reciprocated to and fro upon the floor or support 12 during the rocking operation and while actuated by the occupant of the chair. A power'shaft 13 is journaled horizontally between the opposite parallel rounds or braces 14: beneath the bottom or seat 15 of the chair and is provided upon each end thereof with a crank 16.

" An angular substantially Vshaped operating lever 17 formed of resilient material such as heavy wire, is provided for each of the rockers, being attached at one end thereof by means of an enlargement or head 18 with the lower face of each of the rockers 11 at a point adjacent one of the rear legs 19 of thechair, the main or straight portion 20 of the lever 17 being maintained in flat normal and substantially constant engagement with the floor 12 as best illustrated in Fig. 1 of the drawings. The other end 21 of the lever 17 is operatively j ournaled upon the crank 16 while a ratchet wheel 22 is keyed to the shaft13 at a point adjacent a weighted fly-wheel 23 freely journaled upon the shaft 13 and carrying a pivoted pawl 2 adapted'for operative engagement with the ratchet wheel 22 A pulley 25 is carried by the fly-wheel 23 upon the side thereof opposite the ratchet wheel 22 and a stop collar 26 prevents any relative longitudinal movement of the fly and pulley wheels upon the said shaft. An end or arm 27 .ofthe lever 17 which is angularly disposed with respect to the straight portion 20 of the said lever is curved and freely extends through a vertically-arranged slot 28 in the carrying rocker 11 and the said rocker has a bottom groove or channel 29 whereby the lever '17 is accommodated during the forward movement ofithe said rocker, it being understood that the straight portion 20 of the said lever is at such times bent in an arcuate form for allowing its reception within the said groove 29, the apex portion of the lever being then positioned within the said slot 28. It will thus be evident that the downward rocking movement of the forward portion of the rocker 11 places the straight portion 20 of the lever 17 under tension while an upward rearward motion is imparted to the crank 16 by means of the journaled end 21 of the curved portion 27 of the said lever. Upon the upward return movement of the forward portion of the rocker 11, the straight portion 20 of the lever will by reason of its own resiliency, tend to return to its normally straight position entirely flatly contacting the floor 12 which lowers the journaled end 21 of the lever and thereby affects a complete revolution of the crank 16 and power shaft 13. The lowering of the forward portion of the rocker 11 therefore effects a partial revolution of the crank 16 while the return movement of the lever 17 due to the resiliency thereofcompletes the operation of the crank and a further means for assisting this resilient return movement of the lever will be now described. I

An angular rod 30 has its lower end extended through the rocker slot 28 and secured to the curved arm 27 of the lever 17 at a point 31 adjacent the angular end of the said lever. A helical compression spring 32 is connected between the projecting free end 33 of the rod 30 and a projecting post 34 upon the inner face of the rocker 11. It will thus be evident that the downward I movement of the forward end of the rocker 11 places the spring 32 under tension by extending the same so that upon an upward movement of the forward end of the said rocker 11, the spring 32 assists the lever 17 in returning to its floor-engaging position, allowing the upward movement of the chair round 14 and crank 16 to complete the revolution of the power shaft 13. e

A pulley shaft 35 is journaled in brackets 36 carried by the rear legs 19 of the chair and has a pulley 37 carried thereby over which an endless belt or cord 38 passes for operatively connecting the pulley 37 with the fly wheel pulley 25. Opposite fan brackets 39 are mounted upon the chair back 40, each having an air circulating fan 41 journaled in the forward free end thereof. Each of the fans 41 is provided with a pulley 42 for carrying a cord 43 passing thereover and also over pulley wheels 44 journaled upon stub shafts 45 journaled at opposite sides of the chair back 40. Further pulley wheels 46 are journaled adjacent the outer ends of the stub shafts 45 and endless cords 47 are operatively positioned over the pulley wheels 46 and similar wheels 48 attached to the opposite outer ends of the pulley shaft 35.

The complete operation of the device will be apparent from the above detailed description of the elements and the manner of revolving the power shaft 13, it being seen that the turning of the ratchet wheel 22 moves the power shaft 13 and pulley wheel 25 therewith by means of the pawl 24 when the ratchet wheel 22 is revolving in one direction, being the direction impelled by the lever arm 27, such movement of the crank 16 being upward and rearward with respect to the chair 10. This turning of the pulley 25 revolves the pulley shaft 35, whereby the stub shafts 45 are turned by means of the cords 47 and pulleys 4S and resulting in the consequent revolving of the fans 41 by means of the cords 43 and pulleys 42 and 46. The fans 41 will be revolved in this manner continuously during the rocking movement of the chair 10 and upon the stopping of the movements of the said chair, the fly wheel 23 by reason of its inertia, will continue its movement, thus operating the fans 41 for a short time and with the pawl 24 freely moving over the ratchet wheel 22. Therefore, any slight cessations in the reciprocations of the chair will fail to interrupt the operation of the fans 41 while a restarting of the chair will take up the active operation of the fans.

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is 1. A device of the class described comprising a rocking chair having a curved floor engaging rocker provided with a longitudinal bottom groove terminating in a transverse slot positioned through the forward portion of the said rocker, a power shaft j ournaled beneath the bottom of the said chair, a crank carried by the said shaft, a resilient operating lever extending through the said slot and having one straight arm positioned within the said groove and the other arm having its free end journaled to the said crank, a fan revolubly carried by the said chair, and pawl and ratchet connections between the said shaft and fan.
